Will the nicotine patch really stick?

OBJECTIVE: To determine the incremental cost-effectiveness of the transdermal nicotine patch. DESIGN: Decision analytic model that evaluated the incremental cost-effectiveness of the addition of the nicotine patch to smoking cessation counseling. Costs were based on physician time and the retail cost of the nicotine patch, and benefits were based on quality-adjusted life years (QALYs) saved. PATIENTS: Male and female smokers aged 25 to 69 years receiving primary care. INTERVENTION: Addition of the nicotine patch to physician-based smoking cessation counseling. MAIN OUTCOME MEASURE: Costs (1995 dollars) per QALYs save discounted by 3% annually. RESULTS: The use of the patch produced 1 additional lifetime quitter at a cost of $7332. The incremental cost-effectiveness of the nicotine patch by age group ranged from $4390 to $10 943 per QALY for men and $4955 to $6983 per QALY for women. A clinical strategy involving limiting prescription renewals to patients successfully abstaining for the first 2 weeks improved the cost-effectiveness of the patch by 25%. CONCLUSIONS: The findings provide support both for the routine use of the nicotine patch as an adjunct to physicians' smoking cessation counseling and for health insurance coverage of nicotine patch therapy.

Transdermal oestrogen for treatment of severe postnatal depression.

BACKGROUND: Postnatal depression can have long-term adverse consequences for the mother, for the marital relationship, and for the infant's psychological development. Such depressions can be severe and resistant to both support and counselling and to therapy with antidepressant drugs. We investigated the antidepressant efficacy of oestrogen given transdermally. METHODS: In a double-blind, placebo-controlled study, 61 women with major depression, which began within 3 months of childbirth and persisted for up to 18 months postnatally, were allocated randomly active treatment (n=34; 3 months of transdermal 17 beta-oestradiol 200 micrograms daily alone, then 3 months with added cyclical dydrogesterone 10mg daily for 12 days each month) or placebo (n=27; placebo patches and tablets according to the same regimen). The women were assessed monthly by self-ratings of depressive symptoms on the Edinburgh postnatal depression scale (EPDS) and by clinical psychiatric interview (schedule for affective disorders and schizophrenia [SADS]-change scale). FINDINGS: On pretreatment assessments the women in both groups were severely depressed (mean EPDS score 21.8 [SD 3.0] active group, 21.3 [2.9] placebo group; SADS scores, 66.3 [11.4] and 64.3 [10.7]). During the first month of therapy the women receiving oestrogen improved rapidly, and to a significantly greater extent than controls (mean EPDS scores 13.3 [SD 5.7] vs 16.5 [5.3]. Patients receiving placebo also improved over time but, on average, their scores did not fall below the screening threshold for major depression for at least 4 months. The estimated overall treatment effect of oestrogen on the EPDS was 4.38 points (95% Cl 1.89-6.87). None of a range of other factors (age, psychiatric, obstetric and gynaecological history, severity and duration of current episode of depression, and concurrent antidepressant medication), influenced the response to oestrogen. INTERPRETATION: This study has shown that transdermal oestrogen is an effective treatment for postnatal depression. Further studies are required to establish the minimum effective dose and shortest necessary duration of treatment as well as the mechanism of antidepressant action of oestrogen.
