Assessing patient and caregiver understanding of and satisfaction with the use of contact isolation.

BACKGROUND: Contact isolation is a method used for limiting the spread of antimicrobial-resistant organisms when caring for patients. This policy has been linked to several adverse outcomes and less patient satisfaction. We assessed patient and caregiver understanding and satisfaction with the use of contact isolation. METHODS: A prospective survey of >500 patients in contact isolation at our institution was performed during 2014. Participants responded to a series of statements relating to contact isolation, using a 5-point Likert scale. Responses were assessed for overall positivity or negativity and further compared according to floor type or designation. RESULTS: Of the patients, 48.7% responded to the survey; 70 caregivers also responded. Patient and caregiver responses were similar and were positive overall. Most respondents felt safer because of the use of contact isolation and because it prevented infections. A smaller majority of respondents also thought the policy was adequately explained to them and adhered to by staff. CONCLUSIONS: In the largest collection of respondents surveyed to date about contact isolation and its impact on them, the policy was viewed positively, both by patients and caregivers. There is still room for improvement in the area of patient education regarding the use of contact isolation.

Development of metastatic disease after enrollment in the COMS trials for treatment of choroidal melanoma: Collaborative Ocular Melanoma Study Group Report No. 26.

OBJECTIVE: To describe the time between treatment for choroidal melanoma and first diagnosis of metastatic disease, sites of metastasis, treatments for metastasis, and time between diagnosis of metastasis and death. DESIGN: Prospective, longitudinal follow-up of patients diagnosed with choroidal melanoma who were enrolled in 2 randomized trials conducted by the Collaborative Ocular Melanoma Study Group. METHODS: Systemic and laboratory evaluations were performed during follow-up according to a standard protocol for 2320 patients enrolled in the Collaborative Ocular Melanoma Study trials without evidence of melanoma metastasis or other primary cancer at baseline. RESULTS: Seven hundred thirty-nine patients were diagnosed with at least 1 site of metastasis during follow-up after treatment for choroidal melanoma. Five- and 10-year cumulative metastasis rates were 25% (95% confidence interval, 23%-27%) and 34% (95% confidence interval, 32%-37%), respectively. Liver was the most common site (89%). The death rate following the report of melanoma metastasis was 80% at 1 year (95% confidence interval, 77%-83%) and 92% at 2 years (95% confidence interval, 89%-94%). Overall survival after metastasis did not vary by baseline size of primary tumor nor treatment for metastasis (when known). Long-term survival after diagnosis of metastasis was uncommon; only 8 patients survived 5 or more years. CONCLUSION: Metastasis rate increased significantly with increasing primary tumor dimensions at time of patient enrollment. Prognosis after metastatic disease remains poor. Effective methods are needed to prevent, diagnose, and treat metastasis from choroidal melanoma.

Second primary cancers after enrollment in the COMS trials for treatment of choroidal melanoma: COMS Report No. 25.

OBJECTIVE: To report sites of second primary cancer and the time to first diagnosis during routine follow-up after treatment for choroidal melanoma. DESIGN: Prospective longitudinal follow-up of patients enrolled in 2 randomized trials conducted by the Collaborative Ocular Melanoma Study (COMS) Group. METHODS: Baseline and annual or semiannual systemic and laboratory evaluations were performed according to a standard protocol for 2320 patients enrolled in the COMS without evidence of melanoma metastasis or other primary cancer at baseline. Deaths were coded by a mortality coding committee. RESULTS: Subsequent to treatment for choroidal melanoma, a total of 222 patients were diagnosed with a second primary cancer other than basal or squamous cell skin cancer (5-year rate of 7.7% [95% confidence interval, 6.6%-9.0%]). The most common sites were prostate (23% of reported cases) and breast (17%); 12 of these 222 patients were diagnosed simultaneously with second primary cancers in 2 or more sites. Of these 222 patients, 113 died; 37 (33%) were coded as dead with melanoma metastasis, 33 (29%) as dead with a malignant tumor other than metastatic melanoma, and 13 (11%) as dead with a malignancy of uncertain origin. Radiotherapy did not significantly increase the development of second primary cancers. The rate of diagnosis of second primary cancer did not differ significantly by smoking status, although the rate in former smokers was increased vs that observed in either current smokers or those who never smoked. CONCLUSION: Routine medical surveillance for development of second primary cancers among patients treated for choroidal melanoma is important, especially for those with a history of smoking, regardless of the size of choroidal melanoma at the time of treatment.

Screening for metastasis from choroidal melanoma: the Collaborative Ocular Melanoma Study Group Report 23.

PURPOSE: To describe the predictive value of liver function tests (LFTs), chest x-ray, and diagnostic imaging for detecting melanoma metastasis during routine follow-up after treatment for choroidal melanoma. MATERIALS AND METHODS: Prospective longitudinal follow-up of patients enrolled onto two randomized trials was conducted by the Collaborative Ocular Melanoma Study (COMS) Group. Baseline and annual or semiannual systemic and laboratory evaluations were performed according to a standard protocol for 2320 patients enrolled on the COMS. RESULTS: COMS patients were screened annually for metastasis and new cancers using LFTs (alkaline phosphatase, AST, ALT, or bilirubin). Elevated findings (1.5 to 2 times upper limit of normal) on LFT prompted a diagnostic or imaging test to confirm or rule out cancer recurrence. Of 714 patients with clinical reports of metastasis, 675 patients died. Of these 675 patients, all but four had either histopathologically confirmed or clinically suspected metastatic melanoma present at the time of death. Among all patients, the 5-year cumulative diagnosis rate of metastatic melanoma was 24% (95% CI, 22% to 27%). Based on all patients with reported metastasis, the sensitivity, specificity, positive predictive value and negative predictive value associated with at least one abnormal LFT before first diagnosis of metastasis at any site was 14.7%, 92.3%, 45.7% and 71.0%, respectively. CONCLUSION: Use of LFTs results followed by diagnostic tests has high specificity and predictive values but low sensitivity. Better tests are needed to identify earlier metastatic disease associated with choroidal melanoma.
