Health care safety and quality: where have we been and where are we going?

Health care will always be associated with risk, but the Australian Council for Safety and Quality in Health Care has achieved much in bringing health care safety and quality into public consciousness and beginning systemic change for improvement. Work is underway to develop safety and quality standards, and infrastructure and systems for measurement and evaluation; to increase workforce understanding of how to improve health care delivery; to increase consumer engagement in health care management; and to develop policy and understanding of the barriers to progress. With this foundation of reform, the future of the new Australian Commission on Safety and Quality in Health Care is promising, but it is up to us as health professionals and managers, with the help of the community, to improve the safety and quality of health care.

New surgical consultants: is there a learning curve?

The purpose of this study was to determine whether newly established surgeons who have completed dedicated post-fellowship training are able to achieve surgical outcomes comparable to their more experienced peers. A cross-sectional study of consecutive patients undergoing total thyroidectomy (TT) or completion thyroidectomy was carried out. Outcomes measured included unplanned return to the operating theatre, postoperative infection, permanent recurrent laryngeal nerve (RLN) injury and permanent hypoparathyroidism. Outcomes were categorized according to whether surgery was carried out by an established surgeon (ES) or a newly appointed surgeon (NAS). Eight hundred and nine TT and completion thyroidectomy procedures were carried out in the period January 2002 to December 2004. Of these, 515 (64%) were carried out by ES and 294 (36%) were carried out by NAS. The overall rate of permanent hypoparathyroidism and RLN injury was 1.4% (12/809) and 0.6% (5/809), respectively. The rate of permanent hypoparathyroidism was not significantly different between the two categories of surgeon (ES 1.35% vs NAS 1.7%; P = 0.7). The incidence of permanent RLN injury was not different between the two groups (ES 0.8% vs NAS 0.3%; P = 0.4). For NAS, the rate of permanent RLN injury for the first two years of independent practice did not differ significantly from 3 to 4 years of practice (0/123 vs 1/171; P = 0.4). Indications for surgery between the two groups were similar, with ES carrying out TT for benign goitre in 42% and cancer in 28%, and NAS 44 and 32%, respectively. Surgical outcomes for the newly established endocrine surgeon following subspecialty training are equivalent to those achieved by more experienced surgeons.

Parathyroid autotransplantation during total thyroidectomy--does the number of glands transplanted affect outcome?

Parathyroid autotransplantation is a technique for ensuring the continued function of parathyroid tissue at the time of total thyroidectomy (TT). The aim of this study was to ascertain whether the number of parathyroids transplanted affects the incidence of temporary and permanent hypoparathyroidism. A retrospective cohort study included all patients undergoing a TT in a single unit between July 1998 and June 2003. The number of parathyroids transplanted, the final pathology, and the incidence of temporary and permanent hypoparathyroidism were documented. Fisher's exact test was used for statistical analysis. A total of 1196 patients underwent a TT during the 5 years studied. Of these, 306 (25.6%) had no parathyroids transplanted, 650 (54.3%), 206 (17.2%), 34 (2.8%) had 1,2, or 3 glands autotransplanted, respectively. The incidence of temporary hypoparathyroidism was 9.8% for no gland transplants, 11.9%, 15.1%, and 31.4% for 1,2,and 3 gland transplants, respectively (p < 0.05). The incidence of permanent hypoparathyroidism was 0.98%, 0.77%, 0.97%, and 0%, respectively (p = NS). The incidence of temporary hypoparathyroidism was higher when surgery was performed for Graves' disease. Temporary hypocalcemia is closely related to the number of autotransplanted parathyroids during TT. The long-term outcome is not affected by the number of parathyroids autotransplanted. A "ready selective" approach to parathyroid autotransplantation is an effective strategy for minimizing the rate of permanent hypoparathyroidism.

The Clinical Support Systems Program: supporting system-wide improvement.

The Clinical Support Systems Program (CSSP) provided a mechanism for change from the existing entrenched structure and culture of patient care to one based on patient-centred, evidence-based care. The spectrum of change and improvement achieved by the CSSP was extensive, with support from government and active and enthusiastic involvement of clinical champions, practising clinicians, consumers and managers. The CSSP experience confirmed that responsibility for quality clinical care cannot be borne solely by clinicians, and highlighted key areas where improvement in the support clinicians receive is needed. Many barriers to improvement in our complex healthcare system can be removed by recognising the need for accurate data recording and data systems, teamwork, and high-level organisational buy-in, with collaboration between teams and organisations trying to improve the quality of patient care. System-wide improvement has been stimulated and facilitated by the CSSP experience, with mutual flow-on benefits for the activities of the Australian Council for Safety and Quality in Health Care and the National Institute of Clinical Studies.

Increase in presentations and procedure rates for hyperparathyroidism in Northern Sydney and New South Wales.

OBJECTIVE: To examine changes in presentation of primary hyperparathyroidism and rates of parathyroidectomy in Northern Sydney (the Northern Sydney Area Heath Service) and New South Wales (NSW). DESIGN: Retrospective case series January 1962 - December 2001 and audit of the NSW Department of Health inpatient database (1993-1999). SETTING: University of Sydney Endocrine Surgical Unit, Royal North Shore Hospital. PARTICIPANTS: 1613 patients undergoing parathyroidectomy during the study period. MAIN OUTCOME MEASURES: Age-standardised parathyroidectomy rates and indications for surgical intervention. RESULTS: The age-standardised rates of parathyroidectomy for primary hyperparathyroidism in women have increased significantly in Northern Sydney from 0.14 cases per 100,000 in 1976 to 7.7 cases per 100,000 in 1996 (P < 0.001). In NSW there has been an increase in parathyroidectomy rates in women from 5.1 cases per 100,000 in 1993 to 12.3 cases per 100,000 in 1998 (P < 0.001). Osteoporosis was the most common overall indication for surgery in Northern Sydney, accounting for 27% of all cases. The proportion of cases presenting with osteoporosis increased significantly from 4% in 1962-1980 to 34% over the past decade (P < 0.001). CONCLUSIONS: The rate of parathyroidectomy procedures has increased markedly in Northern Sydney and in NSW. The investigation of osteoporosis has led to the diagnosis of primary hyperparathyroidism in an increasing proportion of cases and has contributed to the growing surgical referral rates.

Minimally invasive parathyroidectomy using the 'focused' lateral approach. I. Results of the first 100 consecutive cases.

BACKGROUND: A feasibility study of 'focused' minimally invasive parathyroidectomy (MIP) using a lateral approach was commenced in 1999. The aim of the present paper was to evaluate the effectiveness and safety of this procedure in the first 100 consecutive patients. METHODS: This was a prospective, non-randomized case-control study. One hundred consecutive patients with primary hyperparathyroidism (mean age 63.1 years; 74 females, 26 males) who fulfilled the inclusion criteria underwent focused MIP between May 1999 and December 2000. The results for the first and last 50 consecutive patients were compared to see whether they were reflective of a learning curve. The role of intraoperative quick parathyroid hormone (QPTH) estimation was also evaluated. RESULTS: Focused MIP was successfully completed in 93 of 100 patients, with seven conversions. Three (3.2%) of the 93 patients had persistent hyperparathyroidism. Quick PTH was measured in 81 patients and the results were true positive (for cure) in 72 patients, false negative in six patients, true negative in two patients and false positive in one patient. Transient recurrent laryngeal nerve paresis occurred in one patient. During the same time period, open parathyroidectomy was performed in 242 patients. The results were not different between the first and later 50 patients undergoing MIP, nor were the outcomes significantly different from patients undergoing open parathyroidectomy. CONCLUSIONS: Focused MIP is a safe and effective operative approach for appropriately selected patients. Failed procedures were invariably related to shortcomings of the localization studies. Measurement of QPTH, although accurate, is unreliable in the presence of multigland disease.

Minimally invasive parathyroidectomy using the 'focused' lateral approach. II. Surgical technique.

BACKGROUND: This paper describes the technique of minimally invasive parathyroidectomy. The technique is based on a thorough understanding of the anatomy of the fascial planes in neck, the surgical pathology and embryology of parathyroid glands and precise anatomical interpretation of preoperative localization studies. METHODS: Tissue trauma is minimized by using a 2.0 cm incision placed directly over the abnormal parathyroid gland and by removing the adenoma, without compromising the basic endocrine surgical principles of identification and preservation of recurrent laryngeal nerve, avoidance of any capsular breech, and ligation of the vascular pedicle. RESULTS/CONCLUSIONS: With proper patient selection, this technique results in a failure rate of less than 4% and ensures that the incidence of complications, such as recurrent laryngeal nerve injury, remains comparable with that of standard open parathyroidectomy.

Minimal access thyroid surgery: is it feasible, is it appropriate?

BACKGROUND: Reports of minimal access thyroid surgery (MATS) using various techniques have recently appeared. This study examined the feasibility of MATS using either a lateral 'focused' or endoscopically assisted approach. METHODS: The study group comprised all patients undergoing minimally invasive parathyroidectomy (MIP) during the period May 1998 to April 2002 in whom a concomitant thyroid procedure was undertaken. All procedures were performed either through a 2-cm lateral cervical incision (n = 19) or endoscopically (n = 7). RESULTS: Twenty-six patients underwent thyroid surgery, consisting of either local excision of a thyroid nodule (n = 25) or hemi-thyroidectomy (n = 1). In 13 patients the nodule was incidentally discovered, in four patients removal of the parathyroid necessitated partial thyroidectomy, and in nine patients the lesion identified by preoperative parathyroid localization proved to be a thyroid nodule. There were no permanent complications in the study group. Two patients required drainage of a haematoma. The final pathology of all 26 cases revealed benign nodular thyroid disease. CONCLUSION: Thyroid surgery can safely be performed as a minimally invasive procedure. Minimal access thyroid surgery is therefore a feasible option for selected patients. The question remains to be answered as to whether this surgical approach is appropriate treatment for nodular thyroid disease.

Two hundred consecutive parathyroid ultrasound studies by a single clinician: the impact of experience.

OBJECTIVE: To assess the ability of ultrasound studies, performed by an experienced clinician, to predict surgical findings and provide precise anatomic localization of abnormal parathyroid glands. METHODS: We retrospectively examined 200 consecutive parathyroid ultrasound studies performed by a single experienced clinician in our unit. All patients subsequently underwent parathyroidectomy, with histopathologic confirmation of abnormal parathyroid tissue. The correlation between the ultrasound and surgical findings was assessed. RESULTS: Of the 200 study patients, 197 (98.5%) were cured of their disease at the initial operation. Ultrasound studies correctly predicted the surgical findings in 88% of patients, including 168 of 180 (93%) with single gland disease and 7 of 20 (35%) with multiple gland disease (MGD). In all cases in which a single adenoma was identified, precise information regarding its location relative to adjacent anatomic structures was provided. In 92% of these cases, anatomic details correlated closely with surgical findings. Ectopic and descended superior adenomas were most frequently missed. Patients with two nonlocalizing studies (scintigraphy and ultrasonography) had a >50% likelihood of having MGD. CONCLUSION: In experienced hands, parathyroid ultrasonography is a highly sensitive technique that provides both localization of enlarged parathyroid glands and precise anatomic detail. Thus, in this study, focused parathyroidectomy was possible in 76.5% of patients. MGD remains difficult to diagnose preoperatively. Nonlocalizing studies should alert the surgeon to a high probability of MGD and prompt the performance of 4-gland exploration.
