The limited effect of screening for depressive symptoms with the PHQ-9 in rural family practices.

CONTEXT: Previous studies have found that routine screening for depression does not improve patient outcome unless it is combined with case management. However, these studies were conducted before the widespread use of SSRIs or in settings other than traditional primary care. PURPOSE: This study investigated whether screening for depressive symptoms improves outcomes for depressed patients seen in rural fee-for-service primary care offices. METHODS: Depression screening was conducted at 2 private rural clinics in Iowa using the PHQ-9. Patients with depressive symptoms were randomized to the control group or the intervention group, where providers were given completed PHQ-9 questionnaires at the baseline visit. The outcome PHQ-9 scores were assessed by telephone at 4, 10, and 24 weeks after the index visit. FINDINGS: A total of 861 patients were screened for depressive symptoms; 51 subjects enrolled in the trial. The intervention and control groups did not significantly differ with respect to changes in PHQ-9 scores at any of the 3 follow-up times. They also did not differ with respect to the proportion of subjects who were actively managed with medication or by referral to a mental health specialist: 46% vs 33% (P = .38) for all subjects and 50% vs 50% (P = .96) for subjects with major depression at baseline. CONCLUSIONS: Screening for depressive symptoms with the PHQ-9 in 2 rural medical clinics did not significantly increase physicians' active management of depression or lead to improved patient outcomes.

Are United States hospitals following national guidelines for the analysis and presentation of cumulative antimicrobial susceptibility data?

The National Committee for Clinical Laboratory Standards recently published guidelines for analysis and presentation of cumulative antimicrobial susceptibility test data (antibiograms). We sought to determine how well US hospitals already adhere to standards for antibiogram compilation, and to examine the relationship between hospital characteristics and guideline adherence. We surveyed laboratory directors at 670 hospitals and examined 3 guideline criteria: compilation of an antibiogram, annual updating, and distribution to infection control staff and medical staff yearly; 494 surveys were returned (74%). Almost all of the hospitals surveyed publish an antibiogram (95%, n = 481); however, only 60% (n = 296) met all three criteria. Hospital laboratories meeting criteria were more likely to serve as referral laboratories (OR = 1.82; 95% CI = 1.26-2.63), perform susceptibility testing on site (OR = 4.47; 95% CI = 1.84-10.84), use confirmatory tests to detect extended-spectrum beta-lactamases (OR = 1.8; 95% CI = 1.2-2.6), and have more laboratory personnel per bed (3.0 vs. 2.0 FTEs/bed, p = 0.0031). Adherence to guidelines for preparation and dissemination of antibiograms could be improved. Institutional commitment to high quality, on-site microbiology laboratory services will improve adherence to these guidelines.

Reporting of medication errors by pediatric nurses.

Medication administration errors can threaten patient outcomes and are a dimension of patient safety directly linked to nursing care. Children are particularly vulnerable to medication errors because of their unique physiology and developmental needs. This descriptive study surveyed a convenience sample of 57 pediatric and 227 adult hospital nurses regarding their perceptions of the proportion of medication errors reported on their units, why medication errors occur, and why medication errors are not always reported. In this study, which focuses on pediatric data, pediatric nurses indicated that a higher proportion of errors were reported (67%) than adult nurses indicated (56%). The medication error rates per 1,000 patient-days computed from actual occurrence reports were also higher on pediatric (14.80) as compared with adult units (5.66). Pediatric nurses selected distractions/interruptions and RN-to-patient ratios as major reasons medication errors occurred. Nursing administration's focus on the person rather than the system and the fear of adverse consequences (reprimand) were primary reasons selected for not reporting medication errors. Results suggest the need to explore both individual and systematic safeguards to focus on the reported causes and underreporting of medication errors.

The effect of case management in substance abuse on health services use.

This study evaluated the effect of case management, as a supplement to traditional substance abuse treatment, on health services utilization. Data for the study were taken from the Iowa Case Management Project (ICMP). The ICMP evaluated case management using a randomized research design. Residential clients who agreed to participate were randomly assigned to one of four case management conditions. The first three conditions were variations of the Iowa Case Management (ICM) model: (a) Inside Case Management, (b) Outside Case Management, and (c) Telecommunications. Case management clients in these three conditions were eligible for 12 months of case management. The fourth condition, the control condition, received no additional case management through ICMP. The study results show that the use of case management decreased the use of mental health services while increasing clients' use of inpatient care, access to physician, and the emergency room. It was expected that case management would increase, in the short run, the substance abuser's use of health services due to staying longer in treatment and seeking medical care that would be otherwise neglected. However, in the long run such early use of necessary health services might reduce the clients' use of avoidable, more costly care. Case management should be looked at as an investment with long-term payoffs.

Participation and retention in drug abuse treatment services research.

We examined potential bias in treatment effectiveness research by studying client characteristics associated with initial participation and subsequent retention in research assessments among clients in substance abuse treatment receiving case management. Six hundred thirty-four residential and 429 outpatient clients were invited to participate. Participants were randomly assigned to one of four conditions. Logistic regression examined the relation between client characteristics and initial participation and retention in follow-up assessments. Females and clients with significant others were more likely to participate and remain in the study. Older persons and criminal justice-referred clients were less likely to participate. Older clients and urban outpatient clients were more likely, and criminal justice-referred clients were less likely, to be retained. Two case management conditions were associated with decreased retention. Client characteristics are important factors in participation and retention in treatment services research. Further, client characteristics may bias estimates of effectiveness generally, or for specific populations.

Effectiveness of case management in substance abuse treatment.

Health officials have promoted case management as a promising intervention in substance abuse treatment (Ridgely & Willenbring, 1992). The relationship between organizational mission combined with case management and different types of outcomes has not been explored in studies, but they are worth noting and exploring further. This study, which is part of a larger clinical trial, examined the 3-, 6-, and 12-month effectiveness of case management in a residential setting for individuals treated for substance abuse. Clients who agreed to participate were randomly assigned to one of four study groups. The groups received face-to-face case management and one telecommunication case management, while the fourth was the control group. Results from the analysis revealed only modest support for the effectiveness of case management as a supplement to traditional treatment. The face-to-face case-managed groups achieved improvements on the legal, employment, and psychiatric domains exceeding that achieved by the control group. Because of the short-term follow-up of the study, conclusive evidence of the effects of case management could not be drawn. This study is a valuable stepping stone, however, to further research in the field and as an aid to policymakers who are interested in knowing more about the effects of case management.

Evaluating the impact of case management dosage.

BACKGROUND: Because of the broad range of activities involved and high variance in clients' needs, it is challenging to measure the actual dose of case management in order to assess quality and manage outcomes. OBJECTIVE: The purpose of this research is to evaluate the impact of intervention dosage on client outcomes in different case management models within substance abuse treatment. METHOD: A descriptive and repeated measures analysis from a clinical trials data set measured the dosage of case management and evaluated impact on client outcomes. A sample of 598 clients from a substance abuse treatment facility was randomized into one of four groups, assessed at intake and then followed for 1 year. Three groups received a form of case management as an intervention (n= 437), and all clients received drug treatment. RESULTS: Clients who engaged (actively participated) in case management were less likely to have legal and family issues but more likely to have a chronic medical condition at baseline. Dosage factors differed significantly across treatment conditions. In general, dose was significantly related to outcomes in the legal and family domains. CONCLUSIONS: Although complex, case management intervention dosage can be measured using the model presented. Dosage determination aids cost-effective initiatives. Further research is needed to specify intervention protocols.

Patient and staff safety: voluntary reporting.

Central to efforts to assure the quality of patient care in hospitals is having accurate data about quality and patient problems. The purpose was to describe the reporting rates of medication administration errors (MAE), patient falls, and occupational injuries. A questionnaire was distributed to staff nurses (N = 1105 respondents) in a national sample of 25 hospitals. This addressed voluntary reporting, work environment factors, and reasons for not reporting occurrences. More than 80% indicated that all MAEs should be reported, but only 36% indicated that near misses should be reported. Perceived levels of actual reporting were: 47% of MAEs, 77% of patient falls, 48% of needlesticks, 22% of other exposures to body fluids, and 17% of back injuries. Administrative response to reports, personal fears, and unit quality management were related to reporting. Patient and staff safety occurrences are underreported. Strong quality management processes and positive responses to reports of occurrences may increase reporting and enhance safety.

The effect of governing board composition on rural hospitals' involvement in provider-sponsored managed care organizations.

Rural hospitals are actively pursuing various strategic alternatives to confront the dramatic changes taking place in the delivery, organization, and financing of healthcare. One of these strategic alternatives is involvement in provider-sponsored managed care organizations. Studies have argued that this form of managed care would enhance public trust and might improve the performance of hospitals. The changing healthcare environment has also increased the importance of the competence and composition of hospital boards. This article examines the effect of the governing board's composition on rural hospitals' involvement in provider-sponsored managed care organizations. The study sample consisted of 140 rural hospitals in Iowa and Nebraska whose CEOs responded to a survey conducted by the Center for Health Services Research at the University of Iowa between June and December 1997. The principal finding was that the likelihood of a hospital owning any form of managed care organization increases with the number of community leaders and health professionals on the board. The number of business leaders had no effect on the likelihood of involvement in such an arrangement. Other factors that affected the likelihood of owning a managed care organization were the health status of the population and ownership type. Key recommendations to managers are to (1) revisit the hospital board's composition before actively pursuing a strategic action, (2) examine the compatibility of the type of strategic activity pursued with the background of board members and the interests of the populations they represent, and (3) use the governing board as a resource in determining which new strategic activities to undertake.
