Whether interventions to improve food access can reduce health care use is unknown.
To determine whether participation in a medically tailored meal intervention is associated with fewer subsequent hospitalizations.
DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study was conducted using near/far matching instrumental variable analysis. Data from the 2011-2015 Massachusetts All-Payer Claims database and Community Servings, a not-for-profit organization delivering medically tailored meals (MTMs), were linked. The study was conducted from December 15, 2016, to January 16, 2019. Recipients of MTMs who had at least 360 days of preintervention claims data were matched to nonrecipients on the basis of demographic, clinical, and neighborhood characteristics.
Weekly delivery of 10 ready-to-consume meals tailored to the specific medical needs of the individual under the supervision of a registered dietitian nutritionist.
Inpatient admissions were the primary outcome. Secondary outcomes were admission to a skilled nursing facility and health care costs (from medical and pharmaceutical claims).
There were 807 eligible MTM recipients. After matching, there were 499 MTM recipients, matched to 521 nonrecipients for a total of 1020 study participants (mean [SD] age, 52.7 [14.5] years; 568 [55.7%] female). Prior to matching and compared with nonrecipients in the same area, health care use, health care cost, and comorbidity were all significantly higher in recipients. For example, preintervention mean (SD) inpatient admissions were 1.6 (6.5) in MTM recipients vs 0.2 (0.8) in nonrecipients (P < .001), and mean health care costs were $80 617 ($312 337) vs $16 138 ($68 738) (P < .001). Recipients compared with nonrecipients were also significantly more likely to have HIV (21.9% vs 0.7%, P < .001), cancer (37.9% vs 11.3%, P < .001), and diabetes (33.7% vs 7.0%, P < .001). In instrumental variable analyses, MTM receipt was associated with significantly fewer inpatient admissions (incidence rate ratio [IRR], 0.51; 95% CI, 0.22-0.80; risk difference, -519; 95% CI, -360 to -678 per 1000 person-years). Similarly, MTM receipt was associated with fewer skilled nursing facility admissions (IRR, 0.28; 95% CI, 0.01-0.60; risk difference, -913; 95% CI, -689 to -1457 per 1000 person-years). The models estimated that, had everyone in the matched cohort received treatment owing to the instrument (and including the cost of program participation), mean monthly costs would have been $3838 vs $4591 if no one had received treatment owing to the instrument (difference, -$753; 95% CI, -$1225 to -$280).
Participation in a medically tailored meals program appears to be associated with fewer hospital and skilled nursing admissions and less overall medical spending.
干预措施是否能改善食物获取以减少医疗保健的使用情况尚不清楚。
确定参与医学定制膳食干预是否与随后的住院次数减少有关。
设计、地点和参与者:使用近/远匹配的工具变量分析进行回顾性队列研究。数据来自 2011-2015 年马萨诸塞州全支付者索赔数据库和非营利组织 Community Servings,该组织提供医学定制膳食(MTM)。研究于 2016 年 12 月 15 日至 2019 年 1 月 16 日进行。至少有 360 天的干预前索赔数据的 MTM 接受者根据人口统计学、临床和社区特征与非接受者进行匹配。
每周提供 10 份符合个人特定医疗需求的即食餐点,由注册营养师监督。
住院是主要结果。次要结果是入住熟练护理机构和医疗保健费用(来自医疗和药品索赔)。
有 807 名符合条件的 MTM 接受者。匹配后,有 499 名 MTM 接受者与 521 名非接受者匹配,共有 1020 名研究参与者(平均[标准差]年龄为 52.7[14.5]岁;568[55.7%]女性)。在匹配前,与同一地区的非接受者相比,接受者的医疗保健使用、医疗保健费用和合并症都明显更高。例如,干预前 MTM 接受者的平均(标准差)住院人数为 1.6(6.5)次,而非接受者为 0.2(0.8)次(P<.001),平均医疗保健费用为 80717 美元(312337 美元),而非接受者为 16138 美元(68738 美元)(P<.001)。与非接受者相比,接受者也更有可能患有艾滋病毒(21.9%比 0.7%,P<.001)、癌症(37.9%比 11.3%,P<.001)和糖尿病(33.7%比 7.0%,P<.001)。在工具变量分析中,MTM 接受与住院人数显著减少相关(发病率比[IRR],0.51;95%CI,0.22-0.80;风险差异,-519;95%CI,-360 至-678 每 1000 人年)。同样,MTM 接受与入住熟练护理机构的人数减少相关(IRR,0.28;95%CI,0.01-0.60;风险差异,-913;95%CI,-689 至-1457 每 1000 人年)。模型估计,如果由于工具(包括参与计划的成本),匹配队列中的每个人都接受治疗,那么如果由于工具没有人接受治疗,每月平均费用将为 3838 美元,而不是 4591 美元(差异,-753 美元;95%CI,-1225 至-280 美元)。
参与医学定制膳食计划似乎与减少住院和熟练护理入院以及总体医疗支出有关。
